I understand that buying advice is partly subjective based on actual need; that being said can someone clue me in whether this is a good/fair price for this particular model Mac Pro. It's the pre-nehalem version, with two Quad-core 3.2ghz Xeons, 4GB ram, 500gb + 1tb HDs, GT120 GPU, Super-drive, and AppleCare through next spring. Is 900$ a good price to pay for this configuration? Obviously my major apprehension is the fact that it is approaching the end of its warranty, and should a logic board go out, it can be quite costly for a college student like myself. Thanks in advance o wise ones.
